The application discloses a heavy door opener with convenient locking and a use method thereof, comprising a heavy door body, a hanging frame system, a hanging rail system and a hanging seat. The heavy door body is provided with a hanging rod on both sides, the door plate hanging frame body of the hanging frame system is provided with a hook device on both sides, and the hanging rod is hung on the lever hook of the hook device. The lever hook is rotated around the shaft rod by driving the opening and closing rotating shaft frame and the pull rod body through pressing the pressing rod, the hanging rod is lifted and pushed into the limiting space of the hanging seat, and the door body is lifted and reliably locked. The end of the pressing rod can be locked by the limiting hole and the pin shaft, and the anti-loosening effect is good. The application adopts a separable hanging structure of the door body and the hanging frame, is convenient to overhaul, is stable in locking, is labor-saving in operation, and supports manual and electric driving.

The application relates to a rack and pinion hoist which solves the problems that the middle trough needs to be manually carried and installed, the operation efficiency is low and the risk is high to some extent. The rack and pinion hoist comprises a bearing plate, a driving mechanism, a hoisting mechanism and a sliding mechanism. The driving mechanism is arranged on the bearing plate, the middle trough is provided with a rack extending along a laying direction, the driving mechanism comprises a driving member and a gear, and the gear is engaged with the rack. The hoisting mechanism comprises a rotating assembly and a hoisting assembly. The rotating assembly is rotationally connected with the bearing plate. The hoisting assembly comprises a first supporting arm and a second supporting arm. One end of the first supporting arm is connected with the rotating assembly and can rotate along with the rotating assembly. One end of the second supporting arm is rotationally connected with the first supporting arm and can be in a folded state with the first supporting arm. The sliding mechanism is arranged on the bottom surface of the bearing plate and is arranged corresponding to the edge step of the middle trough. The sliding mechanism can slide on the edge step and support the bearing plate to keep a horizontal state.

This utility model discloses an elevator guide rail replacement tool, including a fixing mechanism, a pulley block mounted on the fixing mechanism, and a rope wound around the pulley block. Both ends of the rope are free ends with fixed lifting devices for hooking onto the new / old elevator guide rail. The fixing mechanism has an anti-fall-off component for fixing the new guide rail to the existing elevator guide rail. This utility model abandons the traditional electric hoist lifting system, revolutionarily using the bolt holes at the ends of the existing elevator guide rail as lifting points to build a temporary lifting system. This reduces construction costs, eliminates safety risks, eliminates the need for support personnel, saves electricity, and reduces the consumption of wire rope, lubricating oil, etc. Simultaneously, this utility model applies the principle of gravity balance to form a non-powered lifting system, significantly reducing labor intensity, improving construction accuracy, increasing construction efficiency, and exhibiting low operating noise, low construction costs, and energy conservation and environmental protection.

The utility model relates to the technical field of hoisting equipment, and provides a roller hoisting device which comprises a truss used for supporting hoisting of a workpiece; the hoisting piece is horizontally arranged in a sliding mode relative to the truss, and the hoisting piece is arranged in a lifting sliding mode relative to the truss; the two clamping jaws are rotationally arranged relative to the lifting piece, each clamping jaw is provided with an arc-shaped lifting part, and the rotating directions of the two clamping jaws are opposite; after the clamping jaw rotates, the lifting part abuts against or cancels abutting against the workpiece, and the clamping jaw clamps the workpiece or releases the workpiece; according to the technical scheme, the problem that the edge of the roller is scratched when the roller is tilted by a crowbar when the auxiliary roller is lifted in the related technology is solved.

The utility model provides a multifunctional electrophoretic coating workpiece conveying device which comprises a conveying frame, supports are fixedly installed on the left side and the right side of the lower portion of the conveying frame respectively, a rectangular groove is formed in the middle of the conveying frame, a double-track linear motor is fixedly installed on the upper portion of the conveying frame, and a rolling frame assembly is installed on each set of sliding blocks of the double-track linear motor. The winding frame assembly comprises a mounting plate, a side frame is fixedly mounted on the upper portion of the mounting plate, a rotating shaft is mounted in the side frame through a bearing, and a positioning hole is formed in the upper portion of the rear side of the side frame. Due to the arrangement of the mounting plate, the side frame, the positioning hole, the rotating shaft, the winding wheel, the winding rope, the hook, the limiting block, the inserting groove and the electromagnetic brake, a plurality of electrophoretic coating workpieces can be conveyed, and the electrophoretic coating workpieces can be lifted or put down.

The application discloses a textile chemical fiber spinneret cleaning line, which comprises a control cabinet, a transfer device, a TEG cleaning device, a water cleaning device, an alkali cleaning device, an ultrasonic cleaning device and various supporting bracket mechanisms; the transfer device comprises a track moving mechanism, a lifting driving mechanism, a swing driving mechanism, a telescopic overhanging mechanism and a bracket locking mechanism. The textile chemical fiber spinneret cleaning line utilizes the cooperation of the track moving mechanism, the lifting driving mechanism, the swing driving mechanism, the telescopic overhanging mechanism and the bracket locking mechanism, can realize the locking and hoisting of the supporting bracket mechanism, thereby sequentially sends the spinnerets carried on the supporting bracket mechanism into the TEG cleaning device, the water cleaning device, the alkali cleaning device and the ultrasonic cleaning device for corresponding processing, and hoists and takes out the supporting bracket mechanism together with the spinnerets after the processing is completed, greatly reduces the participation of manual work, and effectively improves the batch cleaning efficiency of the spinnerets.
